Qt tableView - add color

Question

How do I add color on the sides of a tableView?

Answer 1

You should subclass QHeaderView and implement your own class like:

#include<QtWidgets>
class HeaderView: public QHeaderView
{
public:
  HeaderView():QHeaderView(Qt::Vertical)
  {}

   void paintSection(QPainter * painter, const QRect & rect, int logicalIndex) const
   {
     QBrush brush;

     if(logicalIndex == 0)
        brush.setColor(QColor(Qt::red));
     else
        brush.setColor(QColor(Qt::blue));

     painter->fillRect(rect, brush); 
     QPen pen(Qt::white);
     painter->setPen(pen);     
     painter->drawText(rect,QString("Row %1").arg(logicalIndex));     
   }
};

Next set an instance of HeaderView as the vertical header of the QTableView:

HeaderView vView;    
tableview.setVerticalHeader(&vView);
